podman update allows users to change the cgroup configuration of an existing container using the already defined resource limits flags from podman create/run. The supported flags in crun are: this command is also now supported in the libpod api via the /libpod/containers/<CID>/update endpoint where the resource limits are passed inthe request body and follow the OCI resource spec format –memory –cpus –cpuset-cpus –cpuset-mems –memory-swap –memory-reservation –cpu-shares –cpu-quota –cpu-period –blkio-weight –cpu-rt-period –cpu-rt-runtime -device-read-bps -device-write-bps -device-read-iops -device-write-iops -memory-swappiness -blkio-weight-device resolves #15067 Signed-off-by: Charlie Doern <cdoern@redhat.com>
